their charts are fine... esignal costs a lot and the IB charts will do.. i guess if you find you want to be more advanced and dont like the charting then you can always get it... good luck with your trading

It all depends on what your strategy is. If it is very basic then Ib charting will do, but if you plan on backtesting or looking at historical data then you better pony up for a third party charting app.
